A Study Of Security Access Technology To Mobile Wireless Network For Smart City

Smart city is the development of modern information and communication technology to a new city form after a certain stage, through the Internet of things of various sensing technology, wireless broadband network of the next generation technology, artificial intelligence and automation technology of polymerization and application integration, the dialogue between man and fabric, and produce more intelligent, automation, information life, industrial development, the social management mode.In this thesis the wisdom of Dalian city management project as an example, discusses the mobile wireless access technology in the process of building a smart city related. Smart city project is a complex project, involving the city management data exchange between various urban management comprehensive law enforcement bureaus, civil affairs, public security, industry and Commerce bureaus, especially the rise of national urban boom.Mobile wireless technology is widely used in the project include wireless local area network WLAN, 3G communication technology, 4G communication technology,networking and wireless access technology, this paper introduces the method to solve the mobile wireless network security access to the 4G, WLAN and the Internet of things and other typical solutions in the project implementation process, including:1 Members of the public access to the urban management, urban management, staff involved in the leadership of the leadership with multiple access using 4G network, in addition to the requirements of telecom operators to provide safe access settings, set the self certified public key system to control the 4G wireless access security compliance, in strict compliance with the relevant security protocols to ensure data security, especially in cross department data transmission;2 Key areas for the free wireless internet access to the public, and personnel access through the WLAN application, based on the summary of the typical technology of the wisdom of urban management, according to the requirement of data transmission confidentiality is very strong, the use of digital authentication certificates and certification system, combined with the unique hardware encryption technology to ensure the security of the wireless network;3 Application of small and medium scale test the project such as the RFID technology of the Internet of things in the trash, poles and other parts of the city in the process of implementation of the Internet of things, the biggest problem of wireless access is facing the problem of heterogeneous network convergence, this article from the network terminal identification and recognition algorithm of the wireless network and the Internet of things,trying to solve the problem of integration step by step, to be in the practice of senior high school entrance examination verification;4 For the city emergency and major events security needs, to bring the wisdom of urban construction opportunity, proposed the mobile ad hoc network as the management scheme and the ability of wisdom city construction.At present, the city of wisdom city management applications have been on-line operation,research progress has been made in at the same time, to further expand the application of wireless access technology in mobile business intelligence, wisdom, the wisdom of the community medical projects, and plans to focus on the integration of heterogeneous wireless networks, to build smart city construction technology, safety management the mechanism, such as a full set of standard system of the wisdom of the city security solutions.
